will it work as a pc moniter?

I purchased this specifically for use as a low cost computer monitor. The 4k resolution works great at 43". I use it for work purposes, not gaming. I doubt it would look good for gaming. My work laptop can only drive it at 30Hz at 4k. I tried it with a personal laptop and for some reason the display did not look good when driven at 60Hz. For office type tasks 30Hz is fine. PDF drawings look great, can view the whole image at once without zooming in.

Can you wall mount this TV?

Indeed. Have myself. I’m not sure any LED/LCD/OLED 4K TV can’t be wall mounted. Just need to buy a wall mount.
